When you power on the headset, keep pressing the Center Button and the (+) Button simultaneously for 3 seconds until you hear three, hightoned beeps. Then you will hear a voice prompt indicating the battery level. However, if you release the buttons as soon as the headset turns on, you will not hear a voice prompt for the battery level indication.

Note:

1. The battery performance may be reduced over time with usage.

2. Battery life may vary depending on conditions, environmental factors, functions of the product in use, and devices used with it.
